Embodiment
Core concept of the present invention is: use the handwriting input with the planar graph real-time follow-up user of boundary rectangle, according to user's handwriting input position that handwriting input device provides, determine the position of planar graph; According to the hand-written velocity correlation information that handwriting input device provides, determine the size of planar graph; According to the hand-written directional correlation information that handwriting input device provides, determine the direction of planar graph, fill the region that planar graph is formed, thus make the stroke of user's handwriting input demonstrate the effect of the vigour of style in writing.
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with embodiment, the present invention is described in more detail.
Fig. 1 shows the flow process that handwriting input in the present invention has the embodiment one of vigour of style in writing effect.
In the present embodiment, the planar graph with boundary rectangle is oval, and the information of user's handwriting input that handwriting input device can provide comprises position coordinates and the time of user's handwriting input.
As shown in Figure 1, the method that handwriting input of the present invention has a vigour of style in writing effect comprises:
Step 11: the span of user's handwriting input speed, the oval size of boundary rectangle and the span of speed zoom factor are set.
Suppose in the present embodiment, according to the actual conditions of user's handwriting input speed, the higher limit arranging user's handwriting input speed is 1 meter per second, lower limit is 0.001 meter per second, namely the scope of user's handwriting input speed is (0.001,1), and unit is meter per second.If the speed of user's handwriting input is slower than 0.001 meter per second, still think that this speed is 0.001 meter per second; If the speed of user's handwriting input is faster than 1 meter per second, still think that this speed is 1 meter per second.
When applying of the present invention, according to different actual conditions, higher limit and the lower limit of different user's handwriting input speed can be set.
According to long edge lengths and the bond length of the boundary rectangle of planar graph, the size of planar graph uniquely can be determined.Wherein, the bond length of boundary rectangle is exactly the width of user's entering stroke, and the width of the entering stroke needed for user, arranges the bond length of boundary rectangle.When arranging bond length, user can directly input concrete length value, also at the width type of pre-designed different stroke, and can arrange the bond length corresponding to width type of different strokes.User as required, selects the width type of different strokes, thus arranges the bond length of boundary rectangle.In the present invention, suppose that the width that user arranges entering stroke is 0.002 meter.
The vigour of style in writing is classified, as the vigour of style in writing is categorized as according to actual vigour of style in writing effect of writing: the ball pen vigour of style in writing, the pen vigour of style in writing and the writing brush vigour of style in writing.User, when handwriting input, selects different vigour of style in writing classification as required, and then the vigour of style in writing classification needed for user, arranges the higher limit of speed zoom factor and the long edge lengths of lower limit and boundary rectangle.
The span of speed zoom factor is larger, the vigour of style in writing effect of user when handwriting input is more obvious, according to the classification of the different vigours of style in writing, higher limit and the lower limit of speed zoom factor are set, determine the span of speed zoom factor and the long edge lengths of boundary rectangle.
When using ball pen to write, the thickness of stroke is substantially constant, the span of speed zoom factor can be set to (1.0,1.0), and be set to identical with bond length by the long edge lengths of the boundary rectangle of the ellipse in the present embodiment, namely 0.002 meter.
When using pen to write, because paper has osmosis, when writing speed is very fast, stroke is comparatively thin, and when writing speed is slower, stroke is thicker.Speed has impact to stroke during pen writing, but impact is relatively little.If user needs vigour of style in writing effect during similar pen writing, then the span of speed zoom factor can be set to (1.0,1.1), and the long edge lengths of the boundary rectangle of the ellipse in the present embodiment is set to identical with bond length, namely 0.002 meter.
When using writing brush to write, if writing speed is fast, then on paper, inking is few, and stroke is comparatively thin, if writing speed is slow, on paper, inking is many, and osmotic effect is obvious, and stroke is thicker.Speed is larger on stroke impact during brush writing.If user needs vigour of style in writing effect during similar brush writing, then the span of speed zoom factor can be set to (0.2,3.0), and the long edge lengths of the boundary rectangle of the ellipse in the present embodiment be set to and 1.2 of bond length times, namely 0.0024 meter.
Step 12: the information provided according to handwriting input device, determines oval position, size and Orientation.
When user writes on handwriting input device, handwriting input device provides the information of user's handwriting input, generally includes position coordinates and the time of the current handwriting input of user.According to the information that handwriting input device provides, follow the tracks of the track of the stroke of user's input, determine oval particular location, size and Orientation.
Suppose that user in a step 11, need vigour of style in writing effect during similar brush writing, the span of speed zoom factor is set to (0.2,3.0), and the long edge lengths of the boundary rectangle of ellipse is set to 0.0024 meter.
According to the parameter arranged in step 11, set up the corresponding relation of handwriting input speed and speed zoom factor.The funtcional relationship supposing handwriting input speed and the speed zoom factor used in the present embodiment is with handwriting input speed for independent variable, and speed zoom factor takes from the inverse of variable.The scope of user's handwriting input speed is (0.001,1), scope according to functional value corresponding to funtcional relationship is (1,1000), (1,1000) are mapped to the span (0.2 of the speed zoom factor set, 3.0), in the present embodiment, adopt the mode of uniform mapping, the reduction formula of writing input speed and speed zoom factor is: the inverse × 0.0028+0.2 of current handwriting input speed.
When applying of the present invention, the funtcional relationship of handwriting input speed and speed zoom factor can also be with handwriting input speed for independent variable, and speed zoom factor takes from the logarithm of variable or the mapping function of other type.In addition, the mapping mode of the function span that handwriting input speed is corresponding and speed zoom factor is not restricted to the uniform mapping mode in the present invention, according to actual needs, can adopt different mapping modes.
In the present embodiment, when user writes, the position that handwriting input device provides user to input in real time and time, according to the mistiming of the distance between user's handwriting input current location and last input position divided by twice position, obtain the current handwriting input speed of user, concrete numerical value does not repeat them here.
Be depicted as example with user writing skimming pen below, the hand-written inputting method realizing vigour of style in writing effect of the present invention is described.
When starting to write, the speed of user writing is comparatively slow, and in order to have obvious vigour of style in writing effect, usual user can use the Writing methods such as reverse row pen.Suppose that the speed of now user writing is increased to 0.01 meter per second gradually by 0.005 meter per second when starting to write.When skimming pen picture write by the oblique descending pen of user, speed speeds gradually, is increased to 0.1 meter per second gradually by 0.07 meter per second.According to the reduction formula of writing input speed and speed zoom factor, speed zoom factor during user's first stroke of a Chinese character is 0.76, and is reduced to 0.28 gradually, user tiltedly descending hourly velocity zoom factor be 0.24 and be reduced to 0.23 gradually.
In the process of user writing, according to current position coordinates and the time of user writing, calculate the input speed that user is current, and then calculate current speed zoom factor, original bond length of the boundary rectangle of ellipse is multiplied with present speed zoom factor respectively with long edge lengths, form the bond length of current boundary rectangle and long edge lengths, obtain the shape of ellipse corresponding to current input.As can be seen from the numerical value change of above-mentioned speed zoom factor, user is when starting to write, and stroke is comparatively thick, and user is when handwriting, and stroke is thinner.
Start to write the process of oblique descending pen from user, according to the current position coordinates of user writing, determine the position of the ellipse that current input is corresponding, the current position coordinates of user writing is defined as the central point of current ellipse.
The current direction inputting corresponding ellipse of user is determined according to the hand-written directional information of user that handwriting input device provides.If the hand-written directional information of the user that handwriting input device provides is directly the deflection that user inputs, then the long side direction of the boundary rectangle of ellipse is set as the direction of this deflection, thus determines oval direction.If the hand-written directional information of the user that handwriting input device provides only provides user the position coordinates inputted, then according to the coordinate of user's handwriting input current location and last input position, computer azimuth angle.The method at calculated direction angle is known technology, does not repeat them here.The deflection this calculated is set as the long side direction of oval boundary rectangle, thus determines the direction of the ellipse that current input is corresponding.
Through said process, in the process of user's handwriting input, oval position, size and Orientation change along with the stroke input of user, and when starting to write, ellipse is comparatively large, and when to receive, ellipse is less, and the direction of ellipse is identical with the direction of user's handwriting input.
Step 13: the region that filled ellipse is formed.
In step 12, according to the stroke of user's handwriting input, determine the ellipse that position, size and Orientation are different, the region of the formation of last filled ellipse.
The oval region formed refers to the region formed by the multiple ellipses determined in step 12.In the region that multiple ellipse is formed, both comprised multiple oval inner scope, also comprised by multiple oval outside subregion, to ensure that finally filled region is level and smooth.
In the present embodiment, the method in the region that filled ellipse is formed is the outer tangent position calculating adjacent ellipses, fills the region surrounded by the outer tangent line of ellipse.When adopting this fill method finally can form level and smooth starting to write, stroke is thick, and when to receive, the thin effect of stroke, makes user obtain vigour of style in writing writing effect true to nature.
If the data that handwriting input device provides are more, the stroke of user's handwriting input can be reflected in the oval region formed, and now, by the area filling in ellipse, can form stroke when starting to write thick, the vigour of style in writing effect that during receipts, stroke is thin.
The region method of the formation of above-mentioned filled ellipse is the known technology of this area, does not repeat them here.In addition, above-mentioned fill method is only preferable examples of the present invention, is not restriction, when applying of the present invention, other just can be adopted to fill the method for planar graph.
Fig. 2 shows the flow process that handwriting input in the present invention has the embodiment two of vigour of style in writing effect.In the present embodiment, the planar graph with boundary rectangle is oval, and the information of user's handwriting input that handwriting input device provides comprises the position coordinates of handwriting input, time and pressure sensitivity.Suppose that the maximum pressure sensitivity progression that the handwriting input device in the present invention provides is 1024, the pressure sensitivity progression scope that the handwriting input device namely in the present embodiment provides is (1,1024).
As shown in Figure 2, the method that handwriting input of the present invention has a vigour of style in writing effect comprises:
Step 21: the span of user's handwriting input speed is set, the size of the span of pressure sensitivity information that handwriting input device provides, oval boundary rectangle and speed zoom factor, pressure sensitivity zoom factor span.Wherein, the setting up procedure of the span of user's handwriting input speed, the size of oval boundary rectangle is identical with embodiment one, does not repeat them here.In the present embodiment, the pressure sensitivity information that handwriting input device provides is pressure sensitivity progression, and its span is (1,1024).
In the present embodiment, classify identical to the classification of the vigour of style in writing with the vigour of style in writing in embodiment one, user, when writing input, selects the classification of the different vigour of style in writing as required, and then the span of the vigour of style in writing classification setting pressure sensitivity zoom factor selected according to user.
During due to use ball pen or pen writing, the shape of nib does not change with the increase of user writing pressure substantially, so when using ball pen or pen writing, the thickness of stroke does not change with the size of pressure sensitivity.At use brush writing, when the pressure sensitivity of user writing is less, use the nib of writing brush to write, stroke is comparatively thin, and when the pressure sensitivity of user writing is larger, use an abdomen for writing brush to write, stroke is thicker.So in vigour of style in writing classification, arrange the span of pressure sensitivity zoom factor for different writing brush vigour of style in writing effects.
In the present embodiment, arrange the span of pressure sensitivity zoom factor for (0.2,2.0), the span of speed zoom factor is (1.0,1.5).When applying of the present invention, also can be different according to the soft or hard degree of writing brush, different pressure sensitivity zoom factors and the span of speed zoom factor are set.
Step 22: the information provided according to handwriting input device, determines oval position, size and Orientation.
According to step 21 kind of the parameter arranged, set up the corresponding relation of handwriting input speed and speed zoom factor.Suppose that the funtcional relationship used in the present embodiment takes from the inverse of variable handwriting input speed.The scope of user's handwriting input speed is (0.001,1), scope according to functional value corresponding to funtcional relationship is (1,1000), (1,1000) are mapped to the span (1.0 of the speed zoom factor set, 1.5), in the present embodiment, adopt the mode of uniform mapping, the reduction formula of speed and speed zoom factor is: the inverse × 1.0005+1.0 of current handwriting input speed.
In the present embodiment, handwriting input speed is similar to the funtcional relationship of speed zoom factor to handwriting input speed in embodiment one to the funtcional relationship of speed zoom factor, does not repeat them here.
Handwriting input device provides the span of pressure sensitivity progression to be (1 in the present embodiment, 1024), by (1,1024) span (0.2 of the pressure sensitivity zoom factor set is mapped to, 2.0), in the present embodiment, adopt the mode of uniform mapping, the reduction formula of pressure sensitivity progression and pressure sensitivity zoom factor is: the pressure sensitivity progression × 0.00176+0.2 of current handwriting input.
In the present embodiment, the uniform mapping mode that handwriting input device provides the mapping mode of pressure sensitivity progression and pressure sensitivity zoom factor to be not restricted in the present invention, according to actual needs, can adopt different mapping modes.
Be depicted as example with user writing skimming pen below, the hand-written inputting method realizing vigour of style in writing effect of the present invention is described.
In the process that user writing skimming pen is drawn, when starting to write, the strength that user writing uses is comparatively large, supposes that the pressure sensitivity progression of now user writing is increased to 800 gradually by 1 when starting to write.User tiltedly descending time, pressure sensitivity is gradually little, is reduced to 1 gradually by 800.According to the reduction formula of pressure sensitivity progression and pressure sensitivity zoom factor, pressure sensitivity zoom factor during user's first stroke of a Chinese character is 0.2, and increases to 1.6 gradually, when user tiltedly descending time pressure sensitivity zoom factor be reduced to 0.2 gradually from 1.6.
Meanwhile, when starting to write, the speed of user writing is increased to 0.01 meter per second gradually by 0.005 meter per second when starting to write.User tiltedly descending time, speed is increased to 0.1 meter per second gradually by 0.07 meter per second.According to the reduction formula of speed and speed zoom factor, speed zoom factor during user's first stroke of a Chinese character is 1.1, and is reduced to 1.05 gradually, when user tiltedly descending time, speed zoom factor is 1.007, and is reduced to 1.005 gradually.Visible the pressure sensitivity information of user's handwriting input is provided at handwriting input device after, speed reduces the impact of the vigour of style in writing effect of user writing.
According to current position coordinates and the time of user writing, calculate the input speed that user is current, and then calculate current speed zoom factor; Pressure sensitivity according to the current location of user writing counts, and calculates the pressure sensitivity zoom factor of the current input correspondence of user; Original bond length according to the boundary rectangle by ellipse is multiplied with current pressure sensitivity zoom factor with present speed zoom factor respectively with long edge lengths, forms the bond length of current boundary rectangle and long edge lengths, obtains the shape of ellipse corresponding to current input.
In the present embodiment, determine that oval position is identical with embodiment one with the method in direction according to current position coordinates and the time of user's handwriting input, do not repeat them here.
Step 23: the region that filled ellipse is formed.
In step 22, according to the stroke track of user's handwriting input, determine the ellipse that size and Orientation is different, last filled ellipse forms track.In the present embodiment, the method for the formation track of filled ellipse change is identical with embodiment one, does not repeat them here.
In the present embodiment, according to velocity information and the pressure sensitivity information of user's handwriting input, calculate oval size, the vigour of style in writing effect that user can be made to input is more true to nature.
When applying of the present invention, if handwriting input device can not provide pressure sensitivity information, only according to the speed of user's handwriting input, the vigour of style in writing effect of user's handwriting input can be realized; If handwriting input device can provide pressure sensitivity information, simultaneously according to speed and the pressure sensitivity of user's handwriting input, the vigour of style in writing effect of user's handwriting input can be realized.The hand-written inputting method realizing vigour of style in writing effect in visible the present invention has larger range of application.
In addition, by the description of above-mentioned two embodiments, the hand-written inputting method realizing vigour of style in writing effect in the present invention calculates relatively simple, thus effectively raises arithmetic speed, makes user obtain happy handwriting input and experiences.
